Purpose: Manual sign is a common alternative mode of communication taught to children with childhood apraxia of speech (CAS). Gesture use is positively related to later increases in vocabulary and syntactic complexity in typical development, but there is little evidence supporting the use of manual sign for children with CAS. We sought to identify…

Minimal expressions are at the heart of interaction: Interjections like "Huh?" and "Mhm" keep conversations flowing by establishing and reinforcing intersubjectivity among interlocutors. Crosslinguistic research has identified that similar interactional pressures can yield structurally similar words (e.g., to initiate repair…

The purpose of this teacher inquiry is to explore the effects of signing and gesturing on the expressive language development of non-verbal children. The first phase of my inquiry begins with the observations of several non-verbal students with various etiologies in three different educational settings. The focus of these observations is to…

A study of three hearing, moderately handicapped children (seven and eight years old) was undertaken in order to examine the acquisition, generalization, and maintenance of sign language production with this population. (PHR)

Videotapes of a deaf child of deaf parents were used to study the developmental stages and underlying processes involved in the child's acquisition of negation from age 28 months to age 41 months. The S was videotaped in spontaneous interaction with her mother or the experimenter for approximately 1 hour each month, and the films were transcribed…

The use of Makaton signs was investigated with 49 British children (ages 4-13) with severe learning difficulties. Teacher-directed settings were associated with more use of signs but limited pragmatic functions. Free play settings were associated with less sign use but more varied functions. In both settings, most spoken and signed language was…
